How about having folders in winbox. Would be great for me that haves alot of connections in it.
please clarify where you want to use folders, and what do you want to put in them?
There is an app for that… “The dude” 
well, we use winbox.
in winbox, we would like to have folders where we can put the routers in them. right now they are in one big list. by putting them in to diffrents folders we maybe can bring order =)
this is the reason we created the Dude. it can be used as a launcher for winbox. there are router groups, maps and whatnot.
i know… but we dont have dude running all the time. Then it is easier to lunch via winbox directly.
another suggestion, create winbox shortcuts on your desktop, or inside subfolders. winbox can launch a connection directly, if you have the parameters this way:
“winbox.exe 12.12.12.12 admin pass”
